KNOCKDOWN BOX AND BLANK THEREFOR.

SPECIFICATION forming part of Letters Patent No. 395,815, dated January 8, 1889. Application filed March 10, 1888. Serial No. 266,875. (Model) T0 aZZ whom it may concern.-

Be it known that I, NANCY J. DoBnINs, a citizen. of the United States of America, rcsiding at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and, useful. Improvenu-mts in Knockdown Boxes and Blanks therefor, of which the following is a specification, reference being had therein to the acconl mnyin drawlugs.

My invention relates to an improved form of knockdown box and to the blank necessary to form the same; and its objects are to furnish a simple and easily-madeblank which may be readily folded into a box adapted to safely and securely hold the contents placed therein and having a handle formed integral with the bodyol the box by extensions of the base thereof; to which ends it consists in the features more particularly hereina Flor described and claimed.

In the drawin are shown my in'iproved box and blank, Figure 1 thereof being a plan View of the blank, while Fig. 2 is a perspective View, on an enlarged scale, of the box set up.

In the figures the folding or crease lines of the blank are indicated by dotted lines,while the cuts therein, as well as its boundaries, are shown in full lines.

In the blank, Fig. 1, the ret'erence-numeral 1 indicates the part which is to be the base or bottom of the completed box, upon one side of which is the wing or extension 2 for forming one side of the box, while upon the other side of l is the wing or extension 3 for the other side of the box, the wing 3 being extended or having joined to it the iiap a,which is to form the lid or cover of the box. Upon the end of 1 is formed the latch-tongue 5, adapted to take and hold in the slot 6 in the wing 2, so as to lock the cover in position. The ends are formed by wings or extensions on each end of the side Wings, there being attached to 3 the extensions 7 8, one of which is formed with the latch-tongue 10 and the other with the slot 9 for receiving the tongue 14, while there are formed on the ends of 2 the extensions 11 12 for forming the other end of the box, one of such extensions being formed with the latch-tongue l4 and the other with the slot 13 for receiving the tongue 10.

Upon the ends of the base 1 are formed the extensions 15 and 17, preferably'of the same width as the base for some little distance, when they are contracted into the straps 16 and 18, one of which is formed with a latchtongue, 19, and the other with a slot, 20, to receive. such tongue. These straps form the handle of the completed box. The lines 21 indicate the folding-lines of the blank. If the box is to be straight, the creasing or folding lines should be parallel; but if it is desired that the box shall be somewhat flaring or inclined the folding-lines of the sides will be somewhat inclined from a to l). r

In setting up the box the sides 2 and 3 are bent upwardly on their crease-lines, and the end extensions, 7 8 and 11. 12, are then bent inwardly, the tongue 14. being interlocked in slot 9 and the tongue 10 in slot The wings 15 17 are also bent upwardly, and it evident that they may be bent upward either without the ends formed by extensions 7 8 and 11 12, as shown, or within the same. To secure the top in position, the latch-tongue 5 is inserted in slot U, while the handle is formed byinserting tongue 19 in the slot 20, which latter may be done either before or after the securement of the top or cover by the engagement of tongue 5 in. slot 6.

Having thus described my invention, what I claim is- 1. A blank for a knockdown box, consisting of the base 1, extensions 2 3 4, for forming the sides and cover, extensions 7 8 11 12, for forming the ends, and extensions 15 16 17 18, for forming a looped handle, substantially as set forth.

A blank for a knockdown box, consisting of a base, 1, side and end extensions, as shown, and prolonged extensions 15 17, attached to the base and having the one a tongue, 19, and the other a slot, 20, for forming a single loop-handle to the box.

The knockdown box herein described,

consisting of the base, the sides attached thereto, the ends and cover attached to the sides, and handle-extensions attached to the base and forming a single loop-handle for the box, substantially as set forth.

In testimony whereof I mysignature in presence of two witnesses.

NANCY J. DOBBINS.
